Tester For Tamper-Evident Closures
Containers
The Orbis digital closure torque tester introduced by Mecmesin in June 2003, has proved extremely popular with quality engineers wishing to capture the torques associated with the first opening.
Containers such as bottles or jars are generally sealed by screw or lug-style closures At various stages during the life cycle of such closures their performance can be characterised by a number of critical torques

Closure-torque testing systems in force
Mecmesin, manufacturer of force and torque test equipment, has developed four new closure-torque testing systems as an extension of its successful Orbis range.
Measure tensile and compressive loading in parts
A particularly cost-effective technique for evaluating manufactured products, materials and components is to measure their ability to sustain applied tensile or compressive loads.
More than materials testng software
Mecmesin's new Imperial test stands controlled by the new generation Emperor software are now available from, and supported by, a worldwide network of Agents.
The original 'Orbis', a digital closure torque tester introduced by Mecmesin in June 2003, has proved extremely popular with quality engineers wishing to capture the torques associated with the first opening, resealing, and re-opening of a closure.
However the torque characteristics of tamper-evident closures are more complex.
Therefore at Total 2004 Mecmesin will be launching an additional instrument especially designed for testing tamper-evident closures.
Consider, for example, the roll-on pilfer-proof (ROPP) aluminium cap used for sealing bottles of alcoholic drink including spirits, and increasingly, wine.
Alternatively consider the aluminium lid and tamper-evident drop-ring sealing a jar of baby food, or the plastic closure sealing a PET soft drink bottle.
When increasing release torque is applied to a closure, a peak torque value is associated with the point at which the closure begins to move.
However in the case of TE-closures, torque must continue to be applied both to overcome friction and to apply tensile load to the 'bridges' connecting the closure to the tamper-evident ring.
Eventually one bridge will fail, and a second (lower) torque peak will occur.
The Orbis TE will capture both peaks.
A single button push will then allow both values to be recorded on a PC or printer. Request a free brochure from Mecmesin ...
